MATRIX-MARKING MACHINE.

To all whom it may concern:

Be it known that we, JOHN SELLERS BAN- oRor'r and lVIAURITZ C. INDAHL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Matrix-Marking Machines; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to automatic means for applying the identifying or distinguishing markings to type machine matrices, more especially the varieties disclosed in Patents Nos. 625,998, dated May 30, 1899 and 784,245, dated March 7, 1905, although applicable in whole or in part to other uses. These matrices, when finished ready for use, consist of small parallelopiped blocks of metal, approximately inch long and inch square, each provided with a cone hole in one end and a matrix cavity in the other end. Each is also provided with either a transverse perforation or circumferental grooves cooperating with the retaining members of the die case. The markings (comprising figures, letters, etc, designating font, set or point dimensions, or other characteristics) are usually countersunk in one or more sides of the block, it being customary heretofore so far as applicants are aware to perform this operation with hammer and punches manipulated by hand, resulting in a more or less irregularity both in position and depth, and a loss of product due to faulty and misplaced markings.

One of the main objects of this invent-ion is to not only render the position of the markings more uniform and regular, but to greatly expedite and cheapen the manufacture, to which ends the invention consists in constructions, combinations and arrangements of parts hereinafter fully described and pointed out in the appended claims.

In the accompanying drawings illustrating a preferred form of embodiment of the several novel features of the invention Figure 1 is a view in perspective. Fig. 2 is a top plan view. Fig. 3 is a right end Specification of Letters Patent. Patented N 14., 1911,

The machine represented in the drawings illustrates a preferred, although not an exclusive, form of embodiment of the present invention, and is specially designed to op.

crate upon and in connection with type machine matrices of the character shown in Figs. 29 and 30 each consisting of a small rectangular block of metal 1, bearing a drive or matrix cavity in one end and a com tering conehole in the opposite end, and pro vided with suitable suspension means in the form of a transverse side hole 2 (Fig. 30) or peripheral grooves 3 (Fig. 29). With the exception of the drive, which of course varies in form and lateral dimensions to correspond with the character and their set and point sizes, all matrices of the same class are of uniform dimensions externally, hence it is desirable to provide each with certain distinguishing markings 4, repre senting characteristics of the individual, such as set and point sizes, font, etc., as well as the line side of the character. This data is utilized in assembling the matrices in the die case and is very difficult to obtain from the drive alone, in the absence of the distinguishing markings, referred to. Ordi narily, each matrix is provided on adjacent sides with two markings 4, pertaining to different series and distinguished by their position in relation to a fixed standard of comparison, such as the side hole 2 or peripheral grooves 3 of different widths.

Heretofore so far as applicants are aware the markings have been separately applied by means of manually controlled hammers and punches, the proper positioning and depth of the impression being dependent entirely upon the skill of the operator. Moreover, much time was consumed both in positioning the matrix to receive the impression, and in properly locating the punch upon the selected face of the matrix, and any error in these respects resulted in a corresponding loss of product. The present machine is designed to automatically perform all the operations incident to the production of said markings save the supplying of the matrices to be operated upon and the selection of the appropriate punches.

Before proceeding to describe the mechanism it may be remarked that the markings are preferably, although not necessarily, applied to the matrices as they are delivered from the driving press (of which examples are to be found in Patent No. 687,779, of December 3, 1901, and application, Serial No. 482,873, filed March 12, 1901) and before the finishing operations are performed;

and, further, that the matrices as delivered by the driving press are discharged sequentially and in corresponding orderly arrangement in a removable galley. When the desired number of characters have been driven by any given punch, the latter is detached from the press and deposited in the receiving galley. The punches being slightly longer than the blanks serve as markers to divide the column into as many sections as there are different drives contained therein, and to indicate the character of the drive in the matrices found associated with each punch.

In the present case the galley 5 containing the matrices and punches as delivered from the press is provided at one end, that most distant from the press, with a spring actuated gate 6 normally closing one end of the channel to prevent accidental displacement of the matrices. The side of said gate is beveled, as at 7, so that when the galley is inserted in the groove or channel provided in the frame of the machine it will contact with a complemental member or projection 8, and be thereby displaced to open the channel and permit the matrices and associated punches to be advanced, so that one end of the column will enter a passage 9 in the frame and advance therein until arrested by the opposite wall of a transverse passage or channel 10. Conveniently, the passages 9 and 10 are formed in a detachable frame 11, and the advance of the column of matrices is effected through the agency of a pusher 12 guided on a rod 13 and coupled by a cord 14 with a pendant weight 15.

Guided to reciprocate on frame 11 within channel 10 is a pusher 16 lying normally to one side of passage 9 in position to engage and advance the innermost matrix through channel 10, said pusher at the same time serving as a gate or cut-off to restrain the forward movement of the column until the pusher shall be again retracted. Passages 9 and 10 are dimensioned to permit free movement of the matrices and to prevent the latter from turning, and passage 10 is preferably equipped with a frictional retainer in the form of spring 17 for sustaining the matrix in upright position while ongaged by pusher 16.

Located in such relation to the advancing column of matrices as to be successively engaged by the punches or markers 18 associated therewith is a feeler or detector 19 whose function it is to automatically arrest the machine after the last matrix in each section has received its marking, thereby preventing the mark intended for one series from being carried forward onto those of another series and at the same time advising the operator that other marking devices or punches should be substituted. Conveniently, feeler 19 is supported in hearings on frame 11 immediately in front of pusher 16 and is arranged to reciprocate in parallel with the latter transversely of passage 9 in a plane just above the matrices and intersecting the path traversed by the projecting section of the punches or markers 18.

The end of channel 10 opposite pusher 16 registers with a similar passage in a guide block 20, the latter preferably formed separate from and detachably secured to a seat on the main frame, said passage communicating with a transverse passage 21 whose cross-section corresponds with that of the matrices. Rigidly secured to the face of guide block 20 is the anvil block 22 provided with an angular or V-shaped seat 23, and fitted to the latter is the wedge shaped punch block 24 grooved or cut away at the point as at 25, to form, in conjunction with the intersection of the walls of seat 23, a passage 26 the walls whereof register with and form prolongations of those of passage 21. Block 24 is also provided with a guide or way 27 perpendicular to each wall of seat 23 for the reception of a marking punch 28. The purpose in thus forming the impressing die in two longitudinal sections, instead of integral, as might otherwise be done, is to permit the ready withdrawal of the section supporting the punches and thereby facilitate inspection and replacement, and with these ends in view block 24 is detachably mounted upon a carrier or frame 29 pivotally connected to the frame, as at 30, and held to working position by a spring actuated bolt 31 engaging a seat 32 on the frame. Bolt 31 is movable radially of axis 30 and is provided with oppositely inclined surfaces 33, through which the bolt may be automatically retracted against the pressure of its spring when force is applied to swing the carrier to retract or advance block 24. Carrier 29 is also equipped with two plungers 34, each located in rear of and in longitudinal alinement with one of the punches 28 to which latter it is connected by a side opening coupling such as that formed by a transverse rib 35 on a projecting portion of plunger 34 entering a transverse slot 36 on one side of punch 28. A spring 37 interposed between a seat on the frame and a shoulder on the plunger serves to retract the latter and with it the con nected punch, to withdraw the latter for the passage of the matrix.

To the upper face of anvil block 22 is secured the finishing die 40 provided with a passage 41 accurately formed to corre spond in cross-section with that of the mat rices to be operated upon, and designed priniarily to correct any deformation of the surface produced by the action of the punches upon the matrices.

its rear with a tail piece or extension 24 resting loosely in a groove or seat 29 1n carrier 29, the outer end of said. tail piece extending beneath an overhanger or bridge 29, as indicated in Figs. 7 and 10. then in working position block 24 is secured against lateral displacement by its engagement with the diverging faces of the anvil block and the proximate faces of guide block 20 and die 40; but when carrier 29 is retracted block 24 can be tilted in its seat, to uncouple the punches from the plungers, after which it is free to be withdrawn from the carrier.

Preferably die 40 is of cylindrical shape and detachably secured, as by pressure, in a seat 42 formed in the under face of a block 43, the latter provided with a rib 44 for en- I gaging a radial notch 45 in the upper face of anvil block 22, the arrangement being such that when blocks 22 and 43 are brought together and secured in'position, die 40 will be accurately located with relation to block 22, so that two adjacent walls of passage 41 will register or be in parallel with the corresponding walls of the angular seat The upper face of block 43 is provided with a transverse way or channel 46 into which the matrix is delivered from die 40. One end of channel 46 communicates with a receiving galley 47 into which latter the matrices are transferred, one at a time, by a pusher 48, said galley being removably supported in a seat on the frame. To prevent the matrix from falling, one side of channel 46, from a point opposite the opening in die 40 to the delivery end, is made yielding, as by the insertion of a movable plate or section 49 secured to screws 50 extending through block 43 or a plate attached thereto and provided with springs 51, the latter To facilitate the insertion and removal of the punches 28 block 24 is provided at operating to advance plate 49 toward the opposite wall of the channel until arrested by the contact of the heads of the screws with block 43 or the attached plate. The space between plate 49 and opposite wall of the channel is normally slightly less than the width of the matrix and the loweredge of said plate is slightly beveled so that as the matrix is delivered into the channel the springs will be compressed.

To the upper face of block 43 is applied the cap plate 52 containing a vertical guide 53 in alinement withthe opening in die 40 and a groove 54 registering with channel 46. Above the delivery end of said channel the under surface of the cap plate is recessed, as at 55, for the reception of a shoe 56, the latter held under the elastic pressure of springs 57 in contact with block 43 and provided on its under side with a groove 58 registering with channel 46, the bottom of said groove being inclined downwardly toward the delivery end of channel 46, the purpose of said incline being to insure the seating of the matrix in channel 46 so that it may enter the receiving galley.

A plunger is guided to reciprocate through passage 21 in the lower guide block (20, while an opposing plunger (51 works through guide 53 in cap plate 52.

Opposite each of the plungers Set is arranged a hammer G1 adapted, when op erated, to engage the head of the plunger and drive the attached punch against a matrix properly positioned on seat 23 of anvil block In the embodiment illustrated each of the hammers is carried upon one arm of a bell crank lever 63 pivotally attached to the frame, as at 64, and provided with an iinpelling spring and a spring actuated retaining latch 66, the latter pivoted to the frame at 67 and engaging and holding one arm of lever (33 when the latter is moved to place spring 65 under tension.

The mechanism. thus far described in eludes what may be termed the operating as distinguished from the actuating devices, and before entering upon a descrip tion of the latter it will be advantageous to explain the cycle of operations to be performed by said operating devices under the control of the actuating devices.

The machine being supplied with a loaded galley 5 and pusher 12 applied to the column of matrices contained therein the inner end of said column will advance through passage 9 until arrested by the opposite wall of passage 10, thus bringing the inner member of the column opposite pusher 16 and the next succeeding member opposite feeler l9. Pusher l6 and feeler 19 are new advanced, the former transferring the inner matrix through passage 10 into passage 21 in guide block 20 above plunger (30, while feeler 19 passes freely over the second member of the column if it is a matrix, and engages and is arrested by said member should it chance to be a punch or marker 18. Plunger 61 is now advanced to its extreme lower or gaging position, and plunger 60 is advanced or elevated until arrested by the contact of the matrix with gaging plunger (31 thus bringing the matrix into position on anvil block seat 23 in proper relation to the punches .28. While the matrix is thus firmly held bet-ween the plungers, catches 66 are operated to release hammers 61 and the latter impinging upon plunger-s 34.: drive the punches 28 into the sides of the matrix. A single stroke of each hammer suffices for the purpose, any secend stroke incident to the rebound being absorbed or cushioned by the punch retracting springs 37. Plunger 61 now retracts and plunger 60 resumes its advance, thereby forcing the marked matrix through die 4L0 into channel 46 in the upper face of block 43 and in front of pusher 48. To insure the matrix clearing the orifice in block 43 the motion of plunger 60 is continued slightly above the floor of channel 46. After ilunger 60 has retracted sufliciently to withdraw from the path of pusher 48 the latter is advanced and delivers the marked matrix into the receiving galley 47, thereby completing the cycle of operations. During the passage of the matrix through die 40 any projections formed on the sides of the matrices incident to the entrance of the punches is flattened down or removed by the action of die 40, and as the matrix is advanced by pusher 48 itis brought down and seated on the floor of channel 46 by shoe 5G engaging the upper end thereof.

The actuating devices which produce and control the movements of the operating members described include two novel and importantfeatures, to-wit; means for automatically arresting the machine when the last matrix of the series for which it is at the time equipped has been operated upon or delivered, to the end that the markings of one series may not be carried over to the members of another series; and means for automatically suspending or preventing the action of the hammers upon the punches when, from any cause, a matrix is not in position to receive the impact of said punches, to prevent mutilation of the punches, their guides or the anvil, such as is liable to occur if no matrix is present.

The actuating mechanism derives motion from two shafts 70, 71 mounted in hearings on the frame and connected through a gear train 73 to rotate in unison and in the same direction. One of said shafts is coupled with a motor device, represented by pulley, 74-, through a one revolution clutch 75 of any known or approved type, provided with a member 76 carried by the driven section and so organized and ar ranged that when engaged by a stop, such as 77, the clutch will open, and when said step is withdrawn the clutch will close automatically. A clutch of this description is illustrated in our application, Serial No. 470,576, filed January at, 1909.

in the present instance stop 77 is pivotally supported upon the frame, and is held normally in the path of unclutching member 76 by a spring 7 8, and is adapted to be swung on its axis and thereby withdrawn from the path of member 76, to permit the closing of the clutch, by a bearing 79 carried by a link 80, the latter coupled with suitable actuating devices, such as foot lever 81, shaft 82 and arm 83. By a longitudinal movement of link 80 stop 77 is tilted to withdraw from engagement with member 76 and so long as this condition is maintained through pressure upon lever 81, the clutch will remain closed and the machine continue in motion. Means may be applied for retaining lever 81 in the depressed or working position but it is preferred that this condition shall be maintained by the action of the operator to insure his presence and avoid loss of time when a change of punches is required.

To pusher 16 is pivoted one end of a rod 8 1 extending through a bearing on a lever 85 the latter carrying a roller engaging cam 86 on shaft'70. A spring 87 is interposed between a bearing 011 rod 81 and one side of lever 85, and said rod carries a head or nut 88 engaging the opposite side of said lever, the arrangement being such that the forward or feeding motion of pusher 16 is transmitted through the spring, while the return motion is transmitted through head 88, hence is positive. To a rear extension of pusher 16 is pivot-ally attached a lever 89 whose opposite end is pivotally connected to the frame through a joint permitting slight movement longitudinally of said lever, to compensate for variations in the distance between the point of attachment to the pusher and point of suspension on the frame due to the right line motion of said pusher, as, for example, by pivoting the lever at 89 to a block 90, the latter in turn pivoted to the frame at 91.

To the rear end of feeler 19 is attached one end of a lever 92 pivoted to lever 89 at 89 intermediate the points of attachment of lever 89 to pusher 16 and block 90, the opposite end of said lever 92 being pivotally coupled with a link 93 opposite the point of attachment of lever 89 to block 90. Link 93 is coupled with link 80 by a pin and slot connection 91 permitting a limited degree of independent motion to said links.

Levers 89 and 92 constitute a pair of floating tongs. So long as no obstruction is placed in the path of feeler 19 the latter is caused to reciprocate in unison with pusher 16 under the influence of lever 85. During such action lever 89 oscillates about pivot 89 and through its connection 89 with lever 92 causes the latter to oscillate about its point of connection with link 93, the latter for the time being held stationary against a shoulder 95 on block 90 by spring 96 acting upon link 80 to retain bearing 79 in contact with unclutching member 76. If, as represented, corresponding arms of levers 89 and 92 on opposite sides of the connecting pivot 89 are equal, the motion of pusher 16 and feeler 19 will be simultaneous and equal in extent. WVhen, however, during the advancing movements of the pusher 16 and feeler 19 the latter is arrested by contact with a marker or punch 18, the fulcrum of lever 92 shifts from the point of attachment to link 93 to that on feeler 19, with the result that during the final movement of said pusher what was before the fulcrum and is now the weight end of lever 92 will be shifted. This motion of lever 92 is transmitted through link 93 to link 80 in a direction to withdraw bearing 79 from its engagement with stop 77, permitting the latter to swing into the path of unclutching member 76, thus opening the latter at the completion of its revolution, despite the circumstance that link 80 maintains its elevated position. It is to be noted in this connection that the so-called floating tongs perform the double function of transmitting motion to the feeler and of transmitting the signal from the feeler to the stopping or unclutching devices.

Preferably the motions are so timed that the feeding motion of pusher 16 takes place after pusher 48 has delivered the previously marked matrix and before unclutching member 76 arrives opposite stop .77 to the end that the last matrix of the series associated with the engaged marker may be completed and delivered before the machine is brought to rest.

Pusher 48 derives motion from opposed cams 97, 97, through lever 98, rod 99, lever 100 and link 101. One side of lever 98 engages a shoulder on rod 99 and the opposite side a spring 102, the latter engaging a shoulder on said rod, the advance or feeding movement of pusher 48 being transmitted through said spring. Gaging plunger 61 receives mot-ion from opposed cams 103, 103, through lever 104, rod 105 and lever 106, the latter engaging the plunger. Between lever 104: and a shoulder on rod 105 is interposed a spring 107, the opposite side of said lever cont-acting with stop 108 on said rod. Motion is transmitted to plunger 60 from opposed cams 109, 109 through lever 110, link 111 and lever 112. This last named lever is coupled to a sleeve 113 carrying a spring 114: and provided with a perforated cap to receive the lower end of plunger 60, the latter provided with a cross-pin 115 riding in a slot in said sleeve and held against the upper end of said slot by the pressure of spring 114, thereby forming a one way yielding coupling between lever 112 and plunger 60.

The hammer actuating connections are controlled by cams 117, 117 and lever 118 as follows: A bell crank lever 119 pivotally supported on the frame has connected to 1 each arm a link 120 the opposite end of the latter slotted to receive a pin 121 on one of the hammer levers 63. One arm of lever 119 is connected by a link 122 to actuating lever 118, the arrangement being such that i when said last named lever is advanced to one extreme of its movement both hammer levers 63 will be retracted to extend their impelling springs 65 and engage retaining latches 66. This setting of the hammers is i effected before plunger 60 completes its first movement of advance to bring the matrix to marking position, and is immediately fol lowed by the recession of lever 119.

Each latch 66 is coupled by a link 123'
